iSAAU G. 'VA'ERMAN, OF Sri est Application ille June 25,

To rtl/f whom, zit' may concern.-

Be it known that l, ienne ili'rnnnan, citizen of the United States, residing Santa Barbara, in the county oi' Santa llarbara and State oi" California, have vented and usefnl Improvements in Electromagnetic Vais/es,

' of which the following is a speciication.

trical systems beforel referred 'to or othei "i This invention relates to electromagnetic valves.

In a series of applications heretofore tiled by me and in patents heretofore granted to me I have set forth certain electrical systems for controlling the flow et' hot and cold water to lavatory-bowls and bath-tubs certain electromagnetic valves need in connection therewith. adapted for controlling` the low in a het or cold Water pipe, and separate electromagnetic valves are used for the het and cold Water pipes.

The present invention contemplates the provision of an improved and novel duplex elecN tromag'netic valve which can be connected to both hot and cold water pipes the same `time and nsed in connection my elecsuitably Wired, thus obviating the neces .ty of using separate electromagnetic vaives the hot and cold water pipes.

A further object of this invention is to provide a novel duplex electromagnetic valve of few parts, compact and durable construction, and reliability ot action.

rhe invention embodies certain Vved features and novel adaptations and. con.. niations oi elements set forth in detaii hereinaf ter, the novel features being;` recited in the appended claims.

in the accompanying` draai/ings, "ure l is a side elevation; Fig. 2, a horizontai section on line X X of Fig. i; i3, acrosssection on line g/ y of Fig. f2, showing certain parte in t'ull lines; Fig. 4, a detail View looking toward the butler on one ot' the partition-disks; Fig. 5, alongitndinal section of niodilica tion; Fig. 6, a longitudinal section oll another modification, and Fig. 7 a eross-section on line Z Z of Fig. 6.

To the valve casing1 or sheii i i the delivery and exit cold-water one side and the delivery and pipes 3 at the other side.

The flow of water through the cold-*water pipes 2 is controlled 4by the turning;` pingvalve 4;, and the dow tliroughhot-water pipes w ,Se

nLOS. Serial No. 153,127.

provided with'integral nuts -1O to facilitateV securing the casing to the pipes. and said cas ing also has the curved magnet-seats li, in which the magnetshells 12 and it?) are secured b vscrews la, the cylindrical iron magnet-shells 12 and 13, each contaiiing` two solenoids 16 and l?, representing the soienoids in 'the shell l2, and 8 and 19 the solenoids in shell i3., all of which have their hollow interiors in allnement and provided with brass tubes 20. rlhe solenoids are suitably insulated by insulating material 2l.

interposed between the adjacent ends of solenoids 16 and l? and between the adjacent ends ot' solenoids 18 and 19 are the respective partition-disks 22 and 23, having the opening of suitable size to permit easy passage of the armatures therethrough in kassembling. These partition-disks have segn mental projections 25, faced with huiiers 25, which extend into the openings -in the respective. solenoids. @n the heads oi the man; net-shells and 13 are projections 2?, having buffers 28.

Extending along the longitudinal center of the openings in the solenoids is a iiat brass separating and guiding strip or plate 29, whose l "s are received in notches 30 in the end tes i the magnet-shells and in similar iteyways or grooves in the tubes 2i), whereby the said strip is lirmly held.

Siidable in the tubi-e120 of the solenoizls 17 and 18 and on one side of the strip Q9 1s an armate re 32, having its [iat side hearing` against the strip 29 and provided with a rack .on its outer side, which meshes with the pinion ci valve 5. rihis armature is controlled' by the solenoids ii' and 18 and limited in its piay by the buticrs 2G.

Un the opposite side or' the strip 29 and slidable in the tubes 2O is a brass bar 34,

on whose rounded outer side is a rack-35, meshing with the pinion of valve 4. 'lo the ends ot' this bar 3e are. secured armatures 36 and 3i', which oi' the same shape in crosssection the har 34.-, and at their ends tney have circular heads 38, illing the inner tubes 20 in the solenoids i6 and 19. These heads are adapted to ahnt on the bniers 3, which limit their play, rlhe joint 39, between the armatures 36 and 37 and the brass bar 34, can
